it does not yet support ioctl() stuff like subsurface needs to do

Ah, that's a bummer.
Yes. So far I see two ideas how to tackle that:
a) extend the "fake devices via regular files" approach by passing along
ioctl() commands.
Seems like a moderate amount of effort, but success is of course unclear
until tried.
I tried this and succeeded to make two exemplary ioctl()s - TCGETS and TCSETS -
work with https://github.com/lvml/makeaoi
When I've got another free time slot I'll find out which ioctl()s
subsurface needs to communicate fine with my own D9, which should
be one of the easier computers to connect to, and see to support
those as well.
If that turns out to work well, I'll see if I can borrow a Bluetooth
connected device for trying.
b) extend unionfs-fuse by CUSE support, trying to pass through the
system devices as user space devices.
I looked up the (not so great) documentation of this, and it won't
work: Only root is allowed to create devices via CUSE.
